1) Remark: Cold-rolled narrow strip made of the alloy steel 25CrMo4 will be delivered in thicknesses up to 6 mm for quenching and tempering and for quenched and tempered cold strip in thicknesses between 0.3 mm and 3.0 mm in following conditions: - soft annealed or soft annealed and little rerolled (+A or +LC), - cold rolled (+CR), - quenched and tempered (+QT). The delivery condition annealed to globular carbides (+AC) can be agreed.
